Overview of outputs and applications.

Application

See also electrical diagrams earlier in the instruction.

DI1

Digital input signal.

The defined function is active when the input is short-circuited/

opened. The function is defined in o02.

DI2

Digital input signal.

The defined function is active when the input is short-circuited/

opened. The function is defined in o37.

S7, S3, S4, S5, S6

Pt 1000 ohm

S7, brine sensor, placed in the cold inlet before the heat exchanger

S3, air sensor, placed in the warm air before the evaporator

S4, air sensor, placed in the cold air after the evaporator

(the need for either S3 or S4 can be deselected in the

configuration)

S5, defrost sensor, placed on the evaporator

S6, product sensor

EKA Display

If there is be external reading/operation of the controller, display

type EKA 163B or EKA 164B can be connected.

RS485 (terminal 51, 52, 53)

For data communication, but only if a data communication

module is inserted in the controller. The module can be a LON

RS485, DANBUSS or a MODBUS.

Terminal 51 = screen

Terminal 52 = A (A+)

Terminal 53 = B (B-)

(For LON RS485 and gateway type AKA 245 the gateway must be

version 6.20 or higher.)

RJ45

For data communication, but only if a TCP/IP module is inserted in

the controller. (OEM)

MODBUS

For data communication.

Terminal 56 = screen

Terminal 57 = A+

Terminal 58 = B-

(Alternatively the terminals can be connected to an external

display type EKA 163A or 164A, but then they cannot be used

for data communication. Any data communication must then be

carried out by one of the other methods.)

Supply voltage

230 V a.c., 50/60 Hz

DO1

Compressor 1

Connection of relay. The coil must be a 230 V a.c. coil.

DO2

Alarm

There is a connection between terminal 7 and 8 in alarm

situations and when the controller is without power.

DO3

Compressor 2

There is connection between terminal 10 and 11 when the

compressor is on.

DO4

Defrost

There is connection between terminal 12 and 14 when

defrosting takes place.

DO5

Fan

There is connection between terminal 15 and 16 when the fan

is on.

Solid state

DO1

Max. 240 V a.c. , Min. 28 V a.c.

output

(for coil)

Max. 0.5 A
